ADJUSTABLE SAFETY-RAZOR.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed October 17, 1910. v Serial No. 587,378.

.Razor s, of which the following is a specification. v. I

My invention relates to razors, andparticularly to that type of razorsknown generallyas safety razors. v

The object of the invention is to simplify the structure of suchdevices, whereby they will not only be cheapened in construction, butwill be more eflicient in use, light in weight, compact in form, made upof a minimum number of parts which are easily assembledor separated forcleaning or replacement of the blade, the parts being of such shape asto be interchangeable, and capable of being manufactured at minimumcost, and whereby the device will be unlikely to get out of re air.

A further object of the invention is to provide in such a deviceadjustment features whereby the blade and guard members may berelatively adjusted, enablin dental objects in view as will more fullyappear in the specification, the invention consists of the featuresof'const-ruction, the

parts and combinations thereof, and the mode of operation, or theirequivalents, as

hereinafter described and set forth in the claims.

Referring to the drawings, Figure 1 is a perspective view of theassembled device.

Fig. 2 is a similar view of the device in reverse position. Fig. 3' is aplan view ofthe assembled device. Fig. 4 is an end elevation thereof.Fig. 5 is a transverse sectional view- Fig. 6 is a longitudinalsectional view. Fig. 7 is a perspective view bar. Fig. 10 is a plan viewof the blade. Figs. 1 to 6 inclusive are drawn on an enlarged scale ofapproximately one-and-onethe user to; shave to different degrees of coseness'.

With the above primary and other incihalf size, while Figs. 7 to 10inclusive are approximately full size.

Like parts are indicated by similar characters of reference throughoutthe several views. I

The instrument forming the subject mat- 1 ter hereof comprises fourseparable parts or members, the blade, the frame member, a binding bar,the blade bein clamped between the binding bar and rame member, and ahandle member having a head portion engaging the binding bar to hold theparts in adjusted posit-ion.

The frame member comprises a central plate portion 1, from theoppositeedges of which project integral arms 2 curved into arch or Ushapesand carrying the marginal toothed or serrated guard strips 3. Thecentral or plate portion of the frame is flat throughout and is providedwith notches or recesses 4 in the opposite ends thereof. Thenotches 4are preferably although not necessarily shouldered as at 5, for theengagement of the binding bar as hereinafter described. The plateportion 1 is provided with a central opening'6. The frame mem-.

-ber is preferably constructed of resilient or spring metal whereby thearched arms 2 will possess a limited degree of elasticity or resiliency.

The marginal guard strips 3 carried by the arms 2 occupy positionsperpendicular to the plane of the central portion 1, and the guardstrips terminate substantially flush or level with the under surface ofthe plate portion 1. The edges of the guard strips 3 are provided with aplurality of regularly spaced notches or recesses, thereby forming aseries of teeth. The said guard strips are of a comb like formation, theends of the teeth terminating level with the inner surface of the plate1 to the plane of which the teeth extend perpendlcularly. Located oneach of the guar strips and projecting inwardly mid'length thereof isprovided in its opposite ends with notches 9 corresponding to thenotches 45 of the frame member. The blade 8 corresponds in length andwidth with the dimensions of the frame-member, the sharpened edges ofthe blade extending substantially flush with the inner faces of theguard strips 3, and the notches 9 registering with the notches 4-5 ofthe frame member when the blade is in position, resting on the plateportion 1 of the frame member. The blade is secured in position on theframe member by the binding bar 10 which comprises a straight barcentrally longitudinally disposed on the outer side of the blade 8, andhaving upwardly and inwardly bent extremities forming inwardlyprojecting lugs 11 extending through the notches 4 and 9 of the frameand blade respectively to a point beyond the plate portion 1 of theframe. The upright portions 12 of the binding bar engage in theshouldered portions 5 of the notches 4 of the frame and likewise in thenotches 9 of the blade. The notches 4 and 9 are of sufficient size topermit the lug 11 of the binding bar to readily pass through saidnotches. The blade 8 is clamped in position between the binding bar andthe plate portion 1 of the frame, and is held in proper alinement withthe frame b the engagement of the ends 12 of the bin ing bar 10 in thenotches 9 of the blade. The handle 13 may be of any suitable shape ormaterial. A transversely arranged head 14 carried on the handle, thelength of which is substantially equal to the interior length of thebinding bar 10 between the upwardly bent ends 12 thereof. On its underside the head 14 is rovided with a projecting stud or pin 15 a apted toengage in the hole 6 in the plate 1 of the frame and form a pivotalconnection upon which the handle 13 and head 14 are revoluble about thelon itudinal axis of the handle 13. The opposite ends of the transversehead 14 are adapted to engage under the inwardly projecting lugs 11 ofthe binding bar to hold the parts 1n assembled position. This isaccomplished by placing'the handle portion on the frame member in adiagonal position as shown in Fig. 3 by dotted lines, with the stud 15of the head engaging in the hole 6 of the frame, and giving to the.

handle and head a partial rotation which causes the extremities of thehead 14 to 1 pass under the lugs 11 of the binding bar as shown in solidlines in said Fig. 3 and as also shown in Figs. 1 and 6. The engagementof the head 14 under the 111 s 11 will hold the parts securely inadjuste position relatively adjusted to enable the user to shave more orless closely, or to compensate for the wearing away of the blade byrepeated sharpening, there is provided upon the head 14, a lateralprojection 16 carrying an inclined or cam shaped head 17 adapted toengage under the inwardly projecting lug 7 of one of the guard strips 3.

The relation of the inclined cam head 17 and the lug 7 is such thatwhenthe head 14 is in its normal position of engagement with the lugs 11of the binding bar, the guard strip will be unaffected. However upon therotation of the handle and head 14 to an extreme position, the oppositeof that shown by dotted lines in Fig. 3, such as to bring the high point18 of the cam head 17 under the lug 7 the guard strip 3 will be elevatedaway from the edge of the blade 8, the spring arms 2 yielding to permitsuch movement. Upon the return r0- tation of the head 14, whereby thecam head 17 is moved from under the lug 7, the spring arms 2 will returnthe guard strip 3 to normal position in proximity to the edge of theblade 8. The relative adjustment of the guard strip and blade may beregulated by giving to the handle and thereby the head 14 and cam head17 a greater or less rotation. The handle 13 and head 14 are reversible,so that the cam head 17 may be made to engage the lug 7 of either of theguard strips 3.

In attaching the handle 13 and head 14, the head'is provided with amortise to be engaged by a tenon 19 on the handle, from which tenon thestud 15 projects, as shown in Fig. 6. This form of connection is onlyincidental, and is not an essential feature of the construction. Inorder that the blade may be tightly clamped at all times, and tocompensate for any slight variation in the thickness of the blade, orWear upon the parts, or any inequalities of manufacture, the ends of thehead 14 are slightly curved upwardly, the h ad being to a slight degreeresilient or flexible. To facilitate the entrance of the ends of thehead 14 under the lugs 11, the advance corners of the head are chamferedas at 21. To maintain the engagement of the head 14 with the lugs 11 ofthe binding bar when the head is rotated to an extreme position for thepurpose of adjusting the guard stri 3, the extremities of the head areprovi ed with lateral extensions 20 which maintain the engagement withthe lugs 11 of the binding bar when the head is in extreme position.

From the above desoriptionitwill be ape,

parent that there is thus produced an instrument of the characterdescribed, possess ing the particular features of advantage beforeenumerated as desirable, but which obviously is susceptible ofmodification in its form, proport1ons,"detail construction, andarrangement of parts withoutdeparting from the principle involved, orsacrificing.

any of its advantages.
